B. Average cost exceeds marginal cost at the minimum efficient scale of plant.
C. When total fixed cost and price are held constant, a rechiction in average variable cost will typically cause a reduction in the breakeven activity level.
D. Anincrease in total fixed cost will alwaysincrease the degree of operatingleverage for firms maling a positive net profit.
E. When longrun average cost is decreasing it can pay to operate smaller plants at their peak efficiency rather than larger plants with some excess capacity.

Question 13

Profit Contribution Analysis. Ben Laden Rugs, Inc., sells hand-made cotton rugs to tourists at a price of $50. Of this amount, $40 is profit contribution. Ben Laden is considering an attempt to differentiate his product from several other competitors by using high quality natural herb dyes. Doing so would increase Ben Laden's unit cost by $15 per rug. Current annual profits are $35,000 on 1,000 rug sales.
A. Assuming average variable costs are constant at all output levels, what is Ben Laden's total cost function before the proposed change?
B. What will the total cost function be if high quality natural herb dyes are used?
C. Assume rug prices remain stable at $50. What percentage increase in sales would be necessary to maintain current profit levels?
